UNLABELLED Down-regulation of the liver-specific MAT1A gene, encoding S-adenosylmethionine (SAM) synthesizing isozymes MATI/III, and up-regulation of widely expressed MAT2A, encoding MATII isozyme, known as MAT1A:MAT2A switch, occurs in hepatocellular carcinoma (HCC). Here we found Mat1A:Mat2A switch and low SAM levels, associated with CpG hypermethylation(More)
AIM To assess the usefulness of self-expandable metal stents in the recanalization of cervical and/or hypopharyngeal strictures. MATERIALS AND METHODS We report our experience in 10 patients with inoperable cervical and/or hypopharyngeal strictures treated by implantation of 11 uncovered self-expandable metal stents inserted perorally under fluoroscopic(More)
PURPOSE To assess the effectiveness of airway stenting performed exclusively under radiological guidance for the palliation of malignant tracheobronchial strictures. METHODS We report our experience in 16 patients with malignant tracheobronchial stricture treated by insertion of 20 Ultraflex self-expandable metal stents performed under fluoroscopic(More)
Hepatocarcinogenesis is under polygenic control. We analyzed gene expression patterns of dysplastic liver nodules (DNs) and hepatocellular carcinomas (HCCs) chemically-induced in F344 and BN rats, respectively susceptible and resistant to hepatocarcinogenesis. Expression profiles were performed by microarray and validated by quantitative RT-PCR and Western(More)
Intrathoracic anastomotic leakage is one of the major complications of esophageal surgery that can lead to high mortality rate. Depending on the clinical presentation, therapeutic options include surgical reintervention and conservative management with or without external drainage or stenting. In this paper, we report a series of three patients, two men and(More)
PURPOSE To assess the usefulness of stereotactic vacuum-assisted core breast biopsy (VCBB) performed using a stereotactic add-on device and film-screen technology with the patient in an upright seated position. MATERIAL AND METHODS We reviewed a series of 129 women with non-palpable mammographic abnormalities who required stereotactic VCBB from December(More)
Neurilemmomas—or schwannomas—are rare soft tissue tumours involving peripheral nerve sheaths, usually found in the head and neck regions. They can infrequently originate within the tissues of the abdominal wall. Here, we present a case of symptomatic schwannoma of the abdominal wall in a 62-year-old woman referred for abdominal pain in the right iliac(More)
BACKGROUND Many cases of gastric perforation with peritonitis, pylephlebitis, hepatic abscesses, or lethal bleeding, caused by ingested long and sharp objects, are reported in the literature. METHODS During a right hepatectomy for a giant hemangioma, a wooden toothpick was found between the two layers of the hepatogastric ligament. It was not possible to(More)
We investigated the effect of different doses of cyclosporin A (CyA) on glucose and insulin levels, as well as its residual effects on pancreatic islets ultrastructure after discontinuation of the drug. We studied four groups of Wistar rats. One control- (n = 5) and three experimental groups, n = 10 each, were treated with different doses of CyA i.m. for 14(More)
The aim of this case report was to evaluate the usefulness of combined biliary and duodenal stenting in the palliation of pancreatic cancer. We report a series of 4 consecutive patients (2 men and 2 women, mean age 58.5 years, range 38-77 years) who underwent combined biliary and duodenal stenting in our department between March 2000 and April 2001.
